List Vercel deployments
AI agents call vercel.deployments_list to retrieve information from MCP Fullstack without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists existing deployments from Vercel. It performs a read-only query with no side effects, no data modification, no code execution, and no destructive operations. The blast radius is minimal—an agent can only discover what deployments exist in a Vercel account, which is informational data retrieval.
From the tool's definition Tool name 'vercel.deployments_list' and description 'List Vercel deployments' indicate a retrieval operation that queries deployment history without modifying any state.

Register the MCP Fullstack MCP server in PolicyLayer and add a rule for vercel.deployments_list: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches MCP Fullstack. Nothing to install.
vercel.deployments_list is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the vercel.deployments_list rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for vercel.deployments_list. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
vercel.deployments_list is provided by the MCP Fullstack MCP server (jacobfv/mcp-fullstack). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
